Question juridique clé
Whether the dispute over reimbursement/coordination of benefits belongs to civil law or public law jurisdiction.
Solution extraite
The claim is governed by public law because it rests on coordination and anti-overinsurance rules of social insurance law, not on private-law claims.
Motifs extraits
The decisive title is the legal basis of the reimbursement claim. Although the parties are an insurer and a pension fund, the recourse mechanism invoked stems from LPGA/LPP coordination rules; these belong to public law. To avoid split jurisdiction, mixed claims must be treated as public-law disputes when their basis lies in social insurance law.
